time over the ethernet interface than the RS-232 interface and signal meters are
more responsive over the ethernet interface). While the SoundStructure Studio
Windows software makes full use of the control protocol to configure and
control SoundStructure, user applications, such as AMX® and Crestron®
control systems will typically only use a subset of the control protocol to adjust
settings and monitor system parameters for functions such as muting, volume
control, and dialing.
RS-232
A SoundStructure device’s RS-232 port is a female DB9 DCE supporting a
fixed data format of eight stop bits, no parity, and one stop bit. The supported
flow control options are hardware (RTS/CTS) and none. The supported baud
rates are 9600, 19200, 38400, 57600, and 115200 with a default baud rate of 9600.
This interface is primarily intended for connecting a control system (such as
AMX or Crestron) to a SoundStructure device. However, other types of
controllers (such as a Windows PC running SoundStructure Studio) may use
this interface as well.
The following figure shows the RS-232 pin-out on the rear-panel of the
SoundStructure device and requirement for a straight-through cable for
connection to an RS-232 port on a control system.
